cpio archive on tape 2

[Perry Whelan]

Hi, I've been wondering this:

I've got a series of tapes (2 tapes) w/ a cpio archive on them, my
command is as follows (from a different OS, hence the 'setblk'):

mt -f /dev/st1 setblk 0 ; cpio -ivdum < /dev/st1

This executes w/o error on tape 1, my question is: why must I start w/
the first tape?

The data I want is on the 2nd tape, if I start w/ the 1st and *then
put in the second tape, when cpio finds the end of volume, it pulls
data off tape 2 no problem (after ~6hr). But, if I try and start w/
tape 2 (using said syntax) it just says skipping xk of junk...

Is there a way to just pull the data from tape 2?

TIA!

- Perry

So, not possible?
